CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. application Ser. No. 15/261,293, filed Sep. 9, 2016, the contents of which is incorporated herein by reference in its entirety.

BACKGROUND

The present disclosure is related to the field of Power Over Ethernet (POE) device system management. More specifically, the present disclosure is related to digital video recorder (DVR) power control in a POE device system.

In current systems, when POE devices, such as remote IP cameras or sensors fail, neither the network switch nor the DVRs are configured to provide a way to power cycle or reset the POE device. In such cases, the system user must dispatch a remote crew to visit the POE device site, and manually reset the POE device and/or the network switch. Such a method and system is very expensive and inefficient.

DETAILED DESCRIPTION OF THE DRAWINGS

In the present description, certain terms have been used for brevity, clearness and understanding. No unnecessary limitations are to be applied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed. The different systems and methods described herein may be used alone or in combination with other systems and methods. Various equivalents, alternatives and modifications are possible within the scope of the appended claims. Each limitation in the appended claims is intended to invoke interpretation under 35 U.S.C. § 112, sixth paragraph, only if the terms “means for” or “step for” are explicitly recited in the respective limitation.

Referring to FIG. 1, the system of the present application adds a feature to DVRs 50 that will use the API of a network switch 60 to power cycle POE to POE devices 70 ported through the network switch 60. This provides a robust capability to recover a POE device 70 such as an IP camera or other POE devices 70 connected to the network switch 60 that have crashed or become non-responsive. This power cycle can be accomplished both automatically and/or manually.

The system improves upon previous system by giving the DVR 50 the capability to automatically power cycle the network switch 60 or any port of the network switch 60 without user input or intervention, thus power cycling any one of a plurality of POE devices 70 through its network switch port. Current systems include switches that only provide this capability by talking to the switch directly (manually). In current practice, there may be over 10,000 DVRs 50 with up to sixty-four POE devices 70 connected to each of the DVRs 50. The DVRs 50 are in many remote locations and currently users need to dispatch repair personnel to reboot POE devices 70 that have gone unresponsive. Due to the fact that many customers decide to install the network switch 60 on an isolated LAN/Switch that only the DVR 50 has access to, the user cannot access the network switch 60 directly.

Referring to FIG. 1 of the present application, a POE device system 10 is illustrated. In such systems, a plurality of POE devices 70 are installed throughout a monitoring area (not shown). The POE device 70 is typically some type of monitoring device such as a camera (in many cases an IP camera), or also could be any other POE device 70 known to be used in such a capacity such as, but not limited to, motion sensors, heat sensors, and noise sensors, among others. As is practical, a group of POE devices 70 are connected to a single network switch 60, wherein each network switch has a dedicated DVR 50. In other systems 10, configurations could be altered slightly such that there are multiple network switches 60 assigned to a single DVR 50, but the system 10 of FIG. 1 illustrates an embodiment where each network switch 60 has a dedicated DVR 50. Depending upon the number of POE devices 70 and network switches 60, the system 10 may have at least one to a plurality of DVRs 50, wherein the DVRs 50 are connected through a wide-area network (WAN) 40, to a remote monitor 30 and a remote user 20. The WAN 40 may be any known network to convey information from the DVRs 50 to the remote monitor 30 and the remote user 20. The WAN 40 may be the cloud or the internet, or any other known network as stated previously.

Still referring to FIG. 1, in operation, the POE devices 70 are running on Ethernet power, and if one goes down, i.e., fails or is unresponsive to the remote monitor 30 or DVR 50, the remote user 20 or the DVR 50 may power cycle the particular port the POE device 70 is using with the API of the network switch 60. The DVR 50 monitors the POE devices 70 using the API of the POE devices 70. This power cycle (or reboot) allows the particular POE device 70 to restart without significant cost or loss of use. It should be noted that any use of the terms nonresponsive or unresponsive is synonymous with any degree of POE device and/or network switch failure, or any degree of POE device 70 and/or network switch 60 responsiveness.

Still referring to FIG. 1, the system 10 may also allow for the DVR 50 and/or the remote user 20 to reboot or power cycle the entire network switch 60. This may be required when a number of the POE devices 70 ported to a particular network switch 60 are down or failing at the same time, or if the network switch 60 itself is unresponsive or failing. The DVR 50 and/or the remote user 20 and remote monitor 30 may also be configured such that when a firmware update is made to the system 10, the DVR 50 automatically power cycles all or a specified number of the network switches 60 after completion of the firmware update. Likewise, the remote user may choose to manually power cycle the network switch 60 at such time as well.

Still referring to FIG. 1, the detection of failure of the POE devices 70 utilizing the API of the POE devices 70 and/or the network switch 60 utilizing the API of the network switch 60 may be configured in the DVR 50, or with a remote monitor 30 connected to the network switches 60 through the WAN 40. In such cases, it is contemplated that the DVR 50 may detect and automatically power cycle the POE device 70 and/or the network switch 60 with the API of the network switch 60, or that the remote monitor 30 may instruct the DVR 50 to carry out the power cycles, or that the remote monitor 30 may prompt a remote user 20 to manually power cycle the network switch 60 and/or the POE devices 70 through the WAN 40. In cases where the DVR 50 is automatically carrying out the power cycling, the DVR does so through the API of the network switch 60.

Referring now to FIG. 2a , a method 100 is illustrated wherein a plurality of POE devices and network switches are monitored with a DVR for failure and/or unresponsiveness in step 105. As discussed above, these POE devices and network switches may be monitored by the DVR or a remote monitor in the system. As stated previously, the POE devices are monitored using the API of the network switches. In step 110, a failure or unresponsiveness of any of the plurality of POE devices or network switches is detected with the DVR (or remote monitor). In step 115, if the reported failure is a failure of a POE device or multiple POE devices, then at step 125, the network switch is instructed to conduct a power cycle of the corresponding parts of the POE device or devices, or of the entire network switch itself, and the power cycle is conducted accordingly. In step 115, if the reported failure is of the network switch, then in step 120, the network switch is instructed to conduct a power cycle or reboot of itself and such power cycle is conducted. Once the appropriate power cycling is completed in steps 120 and/or step 125, then a remote user is notified of the power cycle in step 130, and the method either ends or repeats at step 105.

Referring now to FIG. 2b , the method 100, specifically steps 120 and 125, are described in further detail. In step 120, a remote user of the network switch failure is notified through a remote monitor connected to a DVR and the network switch through a wide-area network (WAN). In step 140, if the system is configured for automatic power cycle, then in step 155 the DVR automatically instructs the network switch to power cycle. If the system is not configured to automatically power cycle, then in step 145, a remote user instructs the network switch to power cycle manually through the WAN and the DVR. In step 160, a power cycle of the network switch is then conducted, and the method moves on to step 130.

In step 125, a remote user is notified of the POEs failure through a remote monitor. In step 170 if the system is configured for automatic power cycle, then in step 180, the DVR automatically determines whether to power cycle the POEs or the network switch according to a predetermined algorithm. In step 170, if the system is not configured to automatically power cycle, then in step 175, a remote user determines whether to power cycle the POEs or the network switch. In both steps 175 and 180, it will be determined whether to power cycle the POEs or the network switch based upon a number of factors including how many POEs for a particular network switch are unresponsive and how many POEs are ported into the particular network switch, among other factors. Step 185 illustrates the situation where the network switch is instructed to power cycle itself after either step 175 or 180, and in step 190, the network switch is instructed to power cycle the POEs. In steps 195 and 197, the network switch and POEs are power cycled, respectively, and the method moves on to step 130.
